Refractory ceramic fibers ndi mtundu wazinthu zosakhazikika za porous zomwe zimakhala ndi zovuta zazing'ono. Kuwunjika kwa ulusi kumangochitika mwachisawawa komanso mopanda dongosolo, ndipo mawonekedwe a geometric osakhazikikawa amabweretsa kusiyanasiyana kwa mawonekedwe awo.
Kuchuluka kwa fiber
Refractory ceramic ulusi wopangidwa ndi magalasi osungunula njira, kachulukidwe ka ulusiwo amatha kuwonedwa ngati wofanana ndi kachulukidwe weniweni. Pamene gulu kutentha ndi 1260 ℃, kachulukidwe ulusi refractory ndi 2.5-2.6g/cm3, ndipo pamene gulu kutentha ndi 1400 ℃, kachulukidwe wa refractory ceramic ulusi ndi 2.8g/cm3. Ulusi wa polycrystalline wopangidwa ndi aluminium oxide uli ndi kachulukidwe kowona kosiyana chifukwa cha kukhalapo kwa ma pores ang'onoang'ono pakati pa tinthu tating'onoting'ono tating'onoting'ono tating'onoting'ono.
Fiber diameter
The fiber diameter yarefractory ceramic ulusiopangidwa ndi kutentha kwambiri kusungunula jekeseni jekeseni njira ranges kuchokera 2.5 kuti 3.5 μ m. Kutalika kwa ulusi wa ulusi wa ceramic wa refractory ceramic fibers opangidwa ndi njira yotentha yotentha kwambiri ndi 3-5 μm. Kutalika kwa ulusi wa refractory sikuli mkati mwamtunduwu, ndipo ulusi wambiri umakhala pakati pa 1-8 μm. The awiri a refractory ceramic ulusi mwachindunji zimakhudza mphamvu ndi matenthedwe madutsidwe wa mankhwala CHIKWANGWANI refractory. Pamene makulidwe a ulusi ndi wokulirapo, zinthu za refractory fiber zimakhala zovuta kuzikhudza, koma kuwonjezereka kwamphamvu kumawonjezeranso matenthedwe. M'zinthu za refractory CHIKWANGWANI, matenthedwe madutsidwe ndi mphamvu ya ulusi amakhala mosagwirizana. Pafupifupi awiri a alumina polycrystalline nthawi zambiri amakhala 3 μ m. Kutalika kwa ulusi wambiri wa ceramic wa refractory ndi pakati pa 1-8 μ.
